Server has 12 well-named tools with consistent verb_noun patterns (get_*, all READ_ONLY). All tools have descriptions (avg ~60 chars, baseline 194 chars) and input schemas with typed parameters. However, descriptions are significantly below baseline length and lack context on WHEN to use each tool or dependencies between them. Output schemas are not documented. Error handling is minimal, no recovery guidance, no actionable error messages. Parameter descriptions are present but terse. No tool annotations (readOnlyHint, etc.) despite all being read-only. Missing pagination guidance for tools returning lists.

• Expand tool descriptions to 100 - 200 chars. Include WHEN to use (e.g., 'Call this to understand individual contributor output. Use get_team_summary for aggregate metrics.'), prerequisites, and what the tool returns. Follow pattern:tool-description.
• Document output schemas for all tools. Add a 'returns' field to each tool definition showing the structure of the response object (e.g., {commits: number, additions: number, deletions: number, filesChanged: number, netChange: number}).
• Add readOnlyHint: true to all tool definitions. This signals to agents that these tools are safe to call without side effects and can be retried freely.
• Enhance error messages in handlers. Replace silent validation failures with actionable errors: 'Invalid repo path: {path}, ensure it exists and is a git repository' and 'Invalid date format: {date}, use YYYY-MM-DD'.
• Add pagination guidance to tools returning lists. Document limit defaults, max values, and whether results are sorted. E.g., 'Returns top N files by change count (default 10, max 100), sorted descending.'
